Description
BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an apparatus for displaying guide line for picture adjustment in a monitor, and more particularly to an apparatus for displaying guide line for picture adjustment in a monitor, which displays a guideline around a periphery of the screen when adjusting the picture, thereby enabling a user to confirm the adjusted result.

2. Description of the Related Art

In general, if a user selects a picture adjustment mode, the on-screen display (OSD) device displays patterns, which are used for displaying specified items for adjusting the picture such as size, position, pin cushion, on the screen.

The user can confirm the varying state of an adjustment value set by himself/herself by means of a numerical value or a bar appearing within the OSD of the picture to display the state of adjustment.

FIG. 1 shows the conventional OSD device for a monitor comprising a control section 11, an OSD generating section 12, an image generator 13, an image amplifier 14 and a display section 15.

The control section 11 is mounted inside of a monitor and outputs a control signal so that the OSD for a picture adjustment mode can be displayed at a predetermined position of the picture in accordance with an input of a picture adjustment menu key by a user. Thus, the control section 11 exchanges data with a system in a main body of a PC. The OSD generating section 12 generates the corresponding OSD in accordance with a control signal from the control section 11. The image generator 13 is mounted on the main body of the PC, and outputs image signals R, G, B to construct a picture corresponding to the control signal from the system in the main body of the PC. The image amplifier 14 combines the OSD image outputted from the OSD generating section 12 with the image signals outputted from the image signal generator 13 to amplify the combined signals. The display section 15 displays an output of the image amplifier on the screen.

The operation of the conventional OSD displaying device for a monitor will now be explained in further detail.

If the user first inputs a picture adjustment menu key through a key input section of the monitor, the control section 11 of the monitor recognizes the input.

The control section 11 locates the position for displaying the OSD in accordance with the horizontal and vertical synchronous signals inputted from the system in the main body of the PC, and outputs a command for generating the OSD to the OSD generating section 12 so that the OSD for picture adjustment mode can be embodied at the corresponding position.

Subsequently, the OSD generating section 12 generates image signals to construct the corresponding OSD in accordance with the control signal outputted from the control section 11 to the image amplifying section 14.

Meanwhile, the image signal generator 13 outputs the image signals R, G, B to the image amplifying section 14, as shown in FIG. 2.

The image amplifying section 14 then combines an output from the OSD generating section 12 with an output from the image signal generator 13, and amplifies the combined outputs to a predetermined level so as to output the amplified image signal to the display section 15.

As shown in FIG. 3, the display section 15 displays the signals outputted from the image amplifying section 14 at a predetermined position of an OSD display window such as in the middle or at a lower portion of the screen undergoing a series of signal processing.

At this time, the user can confirm the picture adjustment result in the picture adjustment mode in accordance with the adjusted value by means of the numerical value or a bar displayed by OSD.

In the picture adjustment mode of a monitor according to the conventional technology, the user can confirm the actual picture adjustment result by using the OSD. However, the actual picture is not clearly distinguished from the entire region of the picture. Thus, the picture adjustment result cannot be easily viewed on the picture, thereby posing a problem of failing to perform a picture adjustment as desired by the user.

An operation of the apparatus for displaying a guide line for picture adjustment according to a first embodiment of the present invention constructed above will now be described in further detail.

The user first inputs a picture adjustment menu key through a key input section of the monitor. The control section 41 of the monitor subsequently recognizes the input.

The control section 41 locates a position to display an OSD in accordance with horizontal and vertical synchronous signals pre-inputted from a system in a main body of a PC. The control section 41 also transfers a command for generating an OSD to the OSD generating section 42 so that an OSD of the picture adjustment mode can be displayed at the corresponding position. At the same time, the control section 41 also transfers a command for generating a guideline to the guideline information providing section 43.

Subsequently, the OSD generating section 42 outputs image signals for constructing the corresponding OSD in accordance with the control signal transferred from the control section 41 to the image amplifying section 45. The guideline information providing section 43 recognizes the command for generating the guideline from the control section 41, and transfers the information related to the guideline such as thickness and color of the guideline to the image signal generator 44.

Accordingly, as shown in FIG. 5, the image signal generator 44 generates image signals, including a guideline signal, image signal and OSD display window embodiment signal in the active region, and outputs the same to the image amplifying section 45.

The image amplifying section 45 combines an output of the OSD generating section 42 with an output of the image signal generator 44, and amplifies the combined signals to a predetermined level so as to be outputted to the display section 46.

As shown in FIG. 6, the display section 46 undergoes a series of signal processing with an output of the image amplifying section 45, and displays the guideline and the OSD around the periphery of the picture so that the user can easily recognize the picture adjustment result.

Embodiment 2

Here, a high-speed detection IC is employed for the active region detector mainly used for auto-sizing.

An operation of the apparatus for displaying guide line for picture adjustment according to the present invention constructed above will now be described herein below.

The user first inputs a picture adjustment menu key through a key input section of the monitor. The control section 71 subsequently recognizes the input.

The control section 71 then outputs a command for generating an OSD to the OSD generating section 72 so that the OSD for a picture adjustment mode can be displayed at the corresponding position. At the same time, the active region detector inside of the monitor 71, e.g., the high-speed detective IC, detects the beginning and ending positions of the active region of the image signals R, G, B supplied from the image signal generator 73. The pattern generator inside of the control section 71 outputs the signal for generating guideline patterns at the corresponding position to the image amplifying section 74.

At this stage, the high speed detective IC detects the image signals R, G, B and synchronous signals from the image signal generator 73, and transfers the information on the exact beginning and ending positions of the active region to the control section 71 upon request of an OSD by the user.

The OSD generating section 72 then outputs the image signal to construct the corresponding OSD to the image amplifying section 74 in accordance with the control signal from the control section 71. The image signal generator 73 outputs the image signals.

Subsequently, the image signal amplifying section 74 combines an output from the OSD generating section 72 and an output from the image signal generator 73 with the guideline pattern signals aud from the control section 71, and amplifies the combined signals so as to be outputted to the display section 75.

As shown in FIG. 6, the display section 75 displays the guideline and the OSD around the periphery of the picture so that the user can easily recognize the picture adjustment result.

The control section 81 can detect information on the beginning and ending positions of the active region in accordance with the horizontal and vertical synchronous signals transferred from a PC system. Thus, the control section 81 outputs the command for generating the OSD and the guideline to the OSD generating section 82 by means of the information on the corresponding position.

The OSD generating section 82 then outputs the image sia to display the corresponding OSD and the guideline to the image amplifying ion 84 in accordance with the control signal from the control section 81. The image signal generator 83 outputs the image signals.

The image signal amplifying section 84 combines the OSD and the guideline image signal outputted from the OSD generating section 82 with the image signals of the image signal generator 83, and amplifies the combined signals to a predetermined level so as to be outputted to the display section 85.

As shown in FIG. 6, the display section 85 undergoes a series of signal processing based on an output of the image amplifying section 84, and displays the guideline and the OSD around the periphery of the picture so that the user can easily recognize the picture adjustment result.

As described above, the Embodiment 1 and the Embodiment 3 provide a guideline for clearly lining the boundary of the picture in a picture adjusting mode, e.g., when adjusting the size of the picture. Thus, the adjusted result clearly appears on the picture.

The result of the picture adjustment may be highlighted by embodying the guideline with a color contrasted with the picture such as a red color.

The apparatus for displaying guide line for picture adjustment in a monitor according to the present invention embodies a guideline around the periphery of the picture in a picture adjustment mode for clearly lining the boundary of the picture.
